Cæsar, satisfied with this success, ordered the retreat to be sounded, and made the tenth legion, which accompanied him, halt (from an examination of the ground, the spot where Cæsar stood is the knoll which rises to the west of the village of Merdogne). (See Plate 21, first position of the tenth legion.) But the soldiers of the other legions, separated from him by a rather wide ravine, did not hear the trumpet. Although the tribunes and the lieutenants did all they could to restrain them, excited by the hope of an easy victory, and by the recollection of their past successes, they thought nothing was insurmountable to their courage, and persisted in the pursuit of the enemy up to the walls and gates of the oppidum.
Then an immense cry arises in the town. The inhabitants of the most remote quarters believe that it is invaded, and rush out of the walls. The matrons throw from the top of the walls their precious objects to the Romans, and, with breasts bare and hands extended in supplication, implore them not to massacre the women and children, as at Avaricum. Several even, letting themselves down from the walls, surrender to the soldiers. L. Fabius, centurion of the 8th legion, excited by the rewards given at Avaricum, had sworn to be the first to mount to the assault; he is lifted up by three soldiers of his company, reaches the top of the wall, and, in his turn, helps them to mount one after the other.
Meanwhile the Gauls, who, as we have seen, had proceeded to the west of Gergovia to raise retrenchments, hear the cries from the town; repeated messages announce the capture of the oppidum. They immediately hurry towards it, sending their cavalry before them. As they arrive, each man takes his stand under the wall and joins the combatants, and their number increases every moment; while the same women who just before implored the pity of the besiegers, now excite against them the defenders of Gergovia, displaying their dishevelled hair and showing their children. The place as well as the numbers rendered the struggle unequal; the Romans, fatigued with their run and the length of the combat, resisted with difficulty troops which were still fresh.
This critical state of things inspired Cæsar with alarm; he ordered T. Sextius, who had been left to guard the little camp, to bring out the cohorts quickly, and take a position at the foot of the mountain of Gergovia, on the right of the Gauls, so as to support the Romans if they were repulsed, and check the enemy’s pursuit. He himself, drawing the 10th legion a little back494 from the place where he had posted it, awaited the issue of the engagement. (See Plate 21, second position of the 10th legion.)
When the struggle was most obstinate, suddenly the Ædui, who had been sent to divert the attention of the enemy by an attack from another side, appeared on the right flank of the Romans. The resemblance of their arms to those of the Gauls caused a great alarm; and although they had their right shoulders bare (dextris humeris exsertis), the ordinary mark of the allied troops, it was taken for a stratagem of the enemy. At the same moment, the centurion L. Fabius, and those who had followed him, are surrounded and thrown down from the top of the wall. M. Petronius, centurion of the same legion, overwhelmed by numbers in his attempt to burst the gates, sacrifices himself for the safety of his soldiers, and meets his death in order to give them time to join their ensigns. Pressed on all sides, the Romans are driven back from the heights, after having lost forty-six centurions; nevertheless, the 10th legion, placed in reserve on more level ground (see Plate 21, third position), arrests the enemies, who are too eager in their pursuit. It is supported by the cohorts of the 13th, who had just taken position on a commanding post (Le Puy-de-Marmant), under the command of the lieutenant T. Sextius. As soon as the Romans had reached the plain, they rallied, and formed front against the enemy. But Vercingetorix, once arrived at the foot of the mountain, ventured no further, but led back his troops within the retrenchments. This day cost Cæsar nearly 700 men.495
Next day, Cæsar assembled his troops, and reprimanded them for their rashness and for their thirst for plunder. He reproached them with having “wished to judge for themselves of the object to be attained, and of the means of attack, and not listening either to the signal of retreat or to the exhortations of the tribunes and lieutenants. He pointed out to them all the importance of the difficulties caused by the inequalities of the ground; and reminded them of his conduct at Avaricum, where, in presence of an enemy without chief and without cavalry, he had renounced a certain victory rather than expose himself to loss, though slight, in a disadvantageous position. Much as he admired their bravery, which had been checked neither by the retrenchments, nor by the steepness of the ground, nor by the walls, he blamed no less their disobedience and their presumption in believing themselves capable of judging of the chances of success and calculating the issue of the undertaking better than their general. He demanded of the soldiers submission and discipline, no less than firmness and bravery; and, to revive their courage, he added that their want of success was to be attributed to the difficulties of the ground much more than to the valour of the enemy.”496
Observations.
VII. In the foregoing account, which is taken almost literally from the “Commentaries,” Cæsar skilfully disguises a defeat. It is evident that he hoped to take Gergovia by a sudden assault, before the Gauls, drawn by a false attack to the west of the town, had time to come back to its defence. Deceived in his expectation, he ordered the retreat to be sounded, but too late to be executed in good order. Cæsar does not appear to be sincere when he declares that he had attained his object the moment his soldiers reached the foot of the wall. This could not have been the case, for what use could it be to him to take camps almost without troops in them, if the consequence was not to be the surrender of the town itself? The defeat appears to have been complete, and, according to some, Cæsar was for a moment a prisoner in the hands of the Gauls; according to others, he had only lost his sword. Servius, indeed, relates the following rather incomprehensible anecdote: when Cæsar was taken away prisoner by the Gauls, one of them began to cry out Cæsar, which signifies in Gaulish let him go, and thus he escaped.497 Plutarch gives another version: “The Arverni,” he says, “still show a sword hung up in one of their temples, which they pretend to be a spoil taken from Cæsar. He saw it there himself subsequently, and only laughed at it. His friends engaged him to take it away, but he refused, pretending that it had become a sacred object.”498 This tradition proves that he was sufficiently great to bear the recollection of a defeat, in which he was very different from Cicero, whom we have seen stealthily taking away from the Capitol the brass plate on which was engraved the law of his banishment.
Cæsar leaves Gergovia in order to join Labienus.
VIII. Cæsar, after the check he had suffered before Gergovia, persisted all the more in his intentions of departure; but, not to have the appearance of flight, he drew out his legions, and placed them in order of battle on an advantageous ground. Vercingetorix did not allow himself to be drawn into the plain; the cavalry only fought, and the combat was favourable to the Romans, who afterwards returned to their camp. The next day the same manœvre was repeated with the same success. Thinking that he had done enough to abate the boasting of the Gauls, as well as to strengthen the courage of his men, Cæsar left Gergovia, and took his way towards the country of the Ædui.
His withdrawal did not draw out the enemies in pursuit; and he arrived on the third day (that is, his second day’s march, reckoning from the assault on Gergovia) on the banks of the Allier, rebuilt one of the bridges, no doubt that of Vichy, and crossed the river in haste, in order to place it between him and Vercingetorix.
There Viridomarus and Eporedorix urged upon him the necessity of their presence among the Ædui, in order to maintain the country in obedience, and to be beforehand with Litavicus, who had gone thither with all the cavalry to excite a revolt. Notwithstanding the numerous proofs of their perfidy, and the suspicion that the departure of those two chiefs would hasten the revolt, he did not think proper to detain them, as he wished to avoid even the appearance of violence or of fear. He confined himself to reminding them of the services which he had rendered to their country, and of the state of dependence and abasement from which he had drawn them, to raise them to a high degree of power and prosperity, and then dismissed them; and they proceeded to Noviodunum (Nevers). This town of the Ædui was situated on the banks of the Loire, in a favourable position. It contained all the hostages of Gaul, the stores, the public treasury, nearly all the baggage of the general and the army, and, lastly, a considerable number of horses bought in Italy and Spain. Eporedorix and Viridomarus heard there, on their arrival, of the revolt of the country, of the reception of Litavicus in the important town of Bibracte by Convictolitavis and a great part of the Senate, as well as of the steps taken to draw their fellow-citizens into the cause of Vercingetorix. The occasion appears favourable to them: they massacre the guards of the dépôt of Noviodunum and the Roman merchants, share amongst themselves the horses and the money, burn the town, send the hostages to Bibracte, load boats with all the grain they can take away, and destroy the rest by water and fire; then they collect troops in the neighbourhood, place posts along the Loire, spread their cavalry everywhere in order to intimidate the Romans, to cut off their supply of provisions, and to compel them through famine to retire into the Narbonnese – a hope which was so much the better founded, as the Loire, swollen by the melting of the snow, appeared to be nowhere fordable.
Cæsar was informed of these events during his march from the Allier towards the Loire. His position had never been more critical. Suffering under a severe defeat, separated from Labienus by a distance of more than eighty leagues, and by countries in revolt, he was surrounded on all sides by the insurrection: he had on his rear the Arverni, elated with their recent success at Gergovia; on his left the Bituriges, irritated by the sack of Avaricum; before him the Ædui, ready to dispute the passage of the Loire. Was he to persevere in his design, or retrograde towards the Province? He could not resolve on this latter course, for not only would this retreat have been disgraceful, and the passage of the Cévennes full of difficulties, but, above all, he felt the greatest anxiety for Labienus and the legions which he had entrusted to him. He therefore persevered in his first resolutions; and in order to be able, in case of need, to build a bridge across the Loire before the forces of the enemies were increased, he proceeded towards that river by forced marches day and night, and arrived unexpectedly at Bourbon-Lancy.499 The cavalry soon discovered a ford which necessity made them consider practicable, although the soldiers had only above water their shoulders and their arms to carry their weapons. The cavalry was placed up the stream, in order to break the current, and the army passed without accident before the enemy had time to recover from his first surprise. Cæsar found the country covered with the harvest and with cattle, with which the army was largely provisioned, and he marched towards the land of the Senones.500
Expedition of Labienus against the Parisii.
IX. Whilst the centre of Gaul was the scene of these events, Labienus had marched with four legions towards Lutetia, a town situated on an island in the Seine, the oppidum of the Parisii. After leaving his baggage at Agedincum (Sens)501 under the guard of the troops recently arrived from Italy to fill up the voids, he followed the left bank of the Yonne and of the Seine, wishing to avoid all important streams and considerable towns.502 At the news of his approach, the enemy assembled in great numbers from the neighbouring countries. The command was entrusted to Aulercus Camulogenus, who was elevated to this honour, notwithstanding his great age, on account of his rare ability in the art of war. This chief, having remarked that a very extensive marsh sloped towards the Seine, and rendered impracticable all that part of the country which is watered by the Essonne, established his troops along the side of this marsh, in order to defend the passage. (See Plate 23.)
When Labienus arrived on the opposite bank, he ordered covered galleries to be pushed forward, and sought, by means of hurdles and earth, to establish a road across the marsh; but, meeting with too many difficulties, he formed the project of surprising the passage of the Seine at Melodunum (Melun), and, when once on the right bank, of advancing towards Lutetia by stealing a march upon the enemy. He therefore left his camp in silence, at the third watch (midnight), and, retracing his steps, arrived at Melun, an oppidum of the Senones, situated, like Lutetia, on an island in the Seine. He seized about fifty boats, joined them together, filled them with soldiers, and entered into the place without striking a blow. Terrified at this sudden attack, the inhabitants, a great part of whom had answered to the appeal of Camulogenus, offered no resistance. A few days before, they had cut the bridge which united the island with the right bank; Labienus restored it, led his troops over it, and proceeded towards Lutetia, where he arrived before Camulogenus. He took a position near the place where Saint-Germain-l’Auxerrois now stands. Camulogenus, informed by those who had fled from Melun, quits his position on the Essonne, returns to Lutetia, gives orders to burn it and to cut the bridges, and establishes his camp on the left bank of the Seine, in front of the oppidum, that is, on the present site of the Hotel de Cluny.
It was already rumoured that Cæsar had raised the siege of Gergovia; the news of the defection of the Ædui, and of the progress of the insurrection, had begun already to spread. The Gauls repeated incessantly that Cæsar, arrested in his march by the Loire, had been compelled, by want of provisions, to retire towards the Roman province. The Bellovaci, whose fidelity was doubtful, had no sooner heard of the revolt of the Ædui, than they collected troops and prepared openly for war.
At the news of so many unfavourable events, Labienus felt all the difficulties of his situation. Placed on the right bank of the Seine, he was threatened on one side by the Bellovaci, who had only to cross the Oise to fall upon him; on the other by Camulogenus, at the head of a well-trained army, ready to give battle; lastly, a large river, which he had crossed at Melun, separated him from Sens, where he had his dépôts and baggage. To escape from this perilous position, he thought it advisable to change his plans: he renounced all offensive movements, and resolved to return to his point of departure by an act of daring. Fearing that, if he went by the road on which he had advanced, he should not be able to cross the Seine at Melun, because his boats would not have re-mounted the river without difficulty, he decided on surprising the passage of the Seine below Paris, and returning to Sens by the left bank, marching over the body of the Gaulish army. Towards evening he convoked a council, and urged on his officers the punctual execution of his orders. He entrusted the boats he had brought from Melun to the Roman knights, with orders to descend the river at the end of the first watch (ten o’clock), to advance in silence for the space of four miles (six kilomètres), which would bring them as far down as the village of Point-du-Joir, and to wait for him. The five cohorts which had least experience were left in charge of the camp, and the five others of the same legion received orders to re-ascend on the right bank of the river in the middle of the night, with all their baggage, and attract by their tumult the attention of the enemy. Boats were sent in the same direction, which were rowed with great noise. He himself, a little after, left in silence with the three remaining legions, and, proceeding down the river, repaired to the spot where the first boats waited for him.
When he arrived there, a violent storm enabled him to carry by surprise the Gaulish posts placed along the whole bank. The legions and cavalry had soon passed the Seine with the assistance of the knights. Day began to appear, when the enemy learnt, almost at the same instant, first, that an unusual agitation prevailed in the Roman camp, that a considerable column of troops was ascending the river, and that in the same direction a great noise of oars was heard; lastly, that lower down the stream the troops were crossing the Seine in boats. This news made the Gauls believe that the legions intended to cross it on three points, and that, perplexed by the defection of the Ædui, they had decided on forcing the road by the left bank.503 Camulogenus divided also his forces into three corps: he left one opposite the Roman camp; sent the second, less numerous, in the direction of Melodunum,504 with instructions to regulate its march according to the progress of the enemy’s boats which re-ascended the Seine; and, at the head of the third, went to meet Labienus.
At sunrise the Roman troops had crossed the river, and the enemy’s army appeared drawn up in order of battle. Labienus exhorts his soldiers to recall to mind their ancient valour, and so many glorious exploits, and, as they marched to the combat, to consider themselves under the eye of Cæsar, who had led them so often to victory: he then gives the signal. At the first shock the 7th legion, placed on the right wing, routs the enemy; but on the left wing, although the 12th legion had transpierced the first ranks with their pila, the Gauls defend themselves obstinately, and not one dreams of flight. Camulogenus, in the midst of them, excites their ardour. The victory was still doubtful, when the tribunes of the 7th legion, informed of the critical position of the left wing, lead their soldiers to the back of the enemies, and take them in the rear. The barbarians are surrounded, yet not one yields a step; all die fighting, and Camulogenus perishes with the rest. The Gaulish troops left opposite the camp of Labienus had hurried forward at the first news of the combat, and had taken possession of a hill (probably that of Vaugirard); but they did not sustain the attack of the victorious Romans, and were hurried along in the general rout; all who would not find refuge in the woods and on the heights were cut to pieces by the cavalry.
After this battle Labienus returned to Agedincum; thence he marched with all his troops, and went to join Cæsar.505
The Gauls assume the offensive.
X. The desertion of the Ædui gave the war a greater development. Deputies are sent in all directions: credit, authority, money, everything is put in activity to excite the other states to revolt. Masters of the hostages whom Cæsar had entrusted to them, the Ædui threaten to put to death those who belong to the nations which hesitate. In a general assembly of Gaul, convoked at Bibracte, at which the Remi, the Lingones, and the Treviri only were absent, the supreme command is conferred on Vercingetorix, in spite of the opposition of the Ædui, who claim it, and who, seeing themselves rejected, begin to regret the favours they had received from Cæsar. But they had pronounced for the war, and no longer dare to separate themselves from the common cause. Eporedorix and Viridomarus, young men of great promise, obey Vercingetorix unwillingly. The latter begins by exacting from the other states hostages to be delivered on a fixed day; orders that the cavalry, amounting to 15,000 men, shall be gathered round his person; declares he has infantry enough at Bibracte, for his intention is not to offer a pitched battle to the Romans, but, with a numerous cavalry, to intercept their convoys of grain and forage. He exhorts the Gauls to set fire with a common accord to their habitations and crops, which are only small sacrifices in comparison to their liberty. These measures having been decided, he demands from the Ædui and the Segusiavi, who bordered upon the Roman province, 10,000 foot soldiers, sends them 800 horse, and gives the command of these troops to the brother of Eporedorix, with orders to carry the war into the country of the Allobroges. On another side, he orders the Gabali and the neighbouring cantons of the Arverni to march against the Helvii, and sends the Ruteni and the Cadurci to lay waste the country of the Volcæ Arecomici. At the same time, he labours secretly to gain the Allobroges, in the hope that the remembrance of their ancient struggles against the Romans is not yet effaced. He promises money to their chiefs, and to their country the sovereignty over the whole Narbonnese.
To meet these dangers, twenty-two cohorts, raised in the province, and commanded by the lieutenant Lucius Cæsar,506 had to face the enemy on every side. The Helvii, faithful to the Romans, by their own impulse, attacked their neighbours in the open field; but repulsed with loss, and having to deplore the death of their chiefs, among others that of C. Valerius Donnotaurus, they ventured no more outside their walls. As to the Allobroges, they defended their territory with energy, by placing a great number of posts along the Rhone. The superiority of the enemy in cavalry, the interruption of the communications, the impossibility of drawing succour from Italy or the province, decided Cæsar on demanding from the German peoples on the other side of the Rhine, subdued the year before, cavalry and light infantry accustomed to fight intermingled. On their arrival, finding that the cavalry were not sufficiently well mounted, he distributed amongst them the horses of the tribunes, and even those of the Roman knights and the volunteers (evocati).507
Junction of Cæsar and Labienus. Battle of the Vingeanne.
XI. The line of march followed by Cæsar after he had crossed the Loire has been the subject of numerous controversies. Yet the “Commentaries” appear to us to furnish sufficient data to determine it with precision. On leaving Gergovia, Cæsar’s object was, as he tells us himself, to effect a junction with Labienus; with this view, he marched towards the land of the Senones, after having crossed the Loire at Bourbon-Lancy. On his part, Labienus, after returning to Sens, having advanced to meet Cæsar, their junction must necessarily have taken place on a point of the line from Bourbon-Lancy to Sens; this point, in our opinion, is Joigny. (See Plate 19.) Encamped not far from the confluence of the Armançon and the Yonne, Cæsar could easily receive the contingent which he expected from Germany.
The Roman army was composed of eleven legions: the 1st, lent by Pompey, and the 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, and 15th.508 The effective force of each of them varied from 4,000 to 5,000 men; for, if we see (lib. V. 49) that on the return from Britain two legions reckoned together only 7,000 men, their effective force was soon increased by considerable re-enforcements which came to the army of Gaul in 702;509 the legion lent by Pompey was of 6,000 men;510 and the 13th, at the breaking out of the civil war, had in its ranks 5,000 soldiers.511 Cæsar had then at his disposal, during the campaigns which ended with the taking of Alesia, 50,000 legionaries, and perhaps 20,000 Numidian or Cretan archers, and 5,000 or 6,000 cavalry, a thousand of whom were Germans, making a total of about 75,000 men, without counting the valets, who were always very numerous.
When the junction of the troops had been effected, Cæsar sought above all to approach the Roman province, in order to carry succour to it with more ease; he could not think of taking the most direct road, which would have led him into the country of the Ædui, one of the centres of the insurrection; he was, therefore, obliged to pass through the territory of the Lingones, who had remained faithful to him, and to proceed into Sequania, where Besançon offered an important place of arms. (See Plate 19.) He started from Joigny, following the road which he had taken when he marched to meet Ariovistus (696),512 and the winter before, when he moved from Vienne to Sens. After reaching the Aube at Dancevoir, he proceeded towards the little river Vingeanne, crossing, as the “Commentaries” say, the extreme part of the territory of the Lingones (per extremos Lingonum fines).513 His intention was, no doubt, to cross the Saône, either at Gray, or at Pontailler.
Whilst the Romans abandoned that part of Gaul which had revolted, in order to approach nearer to the province, Vercingetorix had assembled his army, amounting to more than 80,000 men, at Bibracte; it had come in great part from the country of the Arverni, and counted in its ranks the cavalry furnished by all the states. Having been informed of Cæsar’s march, he started at the head of his troops, to bar the road through Sequania. Passing, as we believe, by Arnay-le-Duc, Sombernon, Dijon, and Thil-Châtel, he arrived at the heights of Occey, Sacquenay, and Montormentier, where he formed three camps, at a distance of 10,000 paces (fifteen kilomètres) from the Roman army. (See Plate 24.) In this position Vercingetorix intercepted the three roads which Cæsar could have taken towards the Saône, either at Gray, or at Pontailler, or at Chalon.514 Resolved on risking a battle, he convoked the chiefs of the cavalry. “The moment of victory,” he told them, “has arrived; the Romans fly into their province, and abandon Gaul. If this retreat delivers us for the present, it ensures neither peace nor rest for the future; they will return with greater forces, and the war will be endless. We must attack them, therefore, in the disorder of their march; for if the legions stop to defend their long convoy, they will not be able to continue their road; or if, which is more probable, they abandon their baggage in order to secure their own safety, they will lose what is indispensable to them, and, at the same time, their prestige. As to their cavalry, they will surely not dare to move away from the column; that of the Gauls must show so much the more ardour, as the infantry, ranged before the camp, will be there to intimidate the enemy.” Then, the cavalry exclaimed, “Let every one swear, by a solemn oath, never to return to the home of his forefathers, his wife, or his children, if he has not ridden twice through the ranks of the enemy!” This proposition was received with enthusiasm, and all took the oath.
The day on which Vercingetorix arrived on the heights of Sacquenay,515 Cæsar, as we have seen, encamped on the Vingeanne, near Longeau. Ignorant of the presence of the Gauls, he started next day, in marching column, the legions at a great distance from each other, separated by their baggage. When his vanguard arrived near Dommarien, it could perceive the hostile army. Vercingetorix was watching the moment they (the Romans) debouched, to attack. He had divided his cavalry in three bodies, and his infantry had descended from the heights of Sacquenay in order to take a position along the Vingeanne and the Badin. (See Plate 24.) As soon as the vanguard of the enemy appears, Vercingetorix bars its way with one of the bodies of cavalry, while the two others show themselves in order of battle on the two wings of the Romans. Taken unexpectedly, Cæsar divides his cavalry also into three bodies, and opposes them to the enemy. The combat engages on all sides; the column of the Roman army halts; the legions are brought into line, and the baggage placed in the intervals. This order, in which the legions were, no doubt, in column of three deep, was easy to execute, and presented the advantages of a square. Wherever the cavalry gives way or is too hotly pressed, Cæsar sends to its support the cohorts, which he draws from the main body to range them in order of battle.516 By this manœuvre he renders the attacks less vigorous, and increases the confidence of the Romans, who are assured of support. Finally, the German auxiliaries, having gained, to the right of the Roman army, the summit of a height (the hill of Montsaugeon), drive the enemies from it, and pursue the fugitives as far as the river, where Vercingetorix stood with his infantry. At the sight of this rout, the rest of the Gaulish cavalry fear to be surrounded, and take to flight. From this time the battle became a mere carnage. Three Ædui of distinction are taken and brought to Cæsar: Cotus, chief of the cavalry, who, at the last election, had contended with Convictolitavis for the sovereign magistracy; Cavarillus, who, since the defection of Litavicus, commanded the infantry; and Eporedorix, whom the Ædui had for chief in their war against the Sequani, before the arrival of Cæsar in Gaul.517
Blockade of Alesia.
XII. Vercingetorix, after the defeat of his cavalry, decided on a retreat; taking his infantry with him, without returning to his camp, he marched immediately towards Alesia, the oppidum of the Mandubii. The baggage, withdrawn from the camp, followed him without delay.518 Cæsar ordered his baggage to be carried to a neighbouring hill, under the guard of two legions, pursued the enemies as long as daylight permitted, killed about 3,000 men of their rear-guard, and established his camp, two days afterwards, before Alesia.519 After having reconnoitred the position of the town, and taking advantage of the disorder of the enemy, who had placed his principal confidence in his cavalry, which was thrown into consternation by its defeat, he resolved to invest Alesia, and exhorted his soldiers to support the labours and fatigues of a siege with constancy.
